Action mechanism of the present utility model is illustrated with embodiment three below.

Close the door action

Door lock A-stage is referring to Fig. 4.When operator closes door closure, the keeper 3 on door closure enters the keyhole 201 of housing 2, Pressure-bearing portion 7021 from keeper head 302 to clamping block 702 apply pressure, the pressure overcome revolution torsion spring 6 stress make clamping block 702 rotationally clockwise, and the front end of lockplate 701 is forced lockplate by the thrust in the slewing limit portion 7024 of clamping block 702 701 move to away from the direction of clamping block 702, when clamping block 702 turns to certain angle, referring to Fig. 5, the slewing limit of clamping block Portion 7024 reaches until crossing when above locking front edge of board 7011, under the effects of back-moving spring I 11, lockplate 701 is to leaning on below The nearly direction of clamping block 702 movement, locking front edge of board 7011 enters the lower section in the slewing limit portion 7024 of clamping block, holds revolution limit Position portion 7024, even if at this moment closing the door thrust releasing, in the presence of back-moving spring II 13, produces lockplate 702 and presses upwards on Power, the power for pressing upwards on is far longer than revolution torsion spring 6 makes the counterclockwise rotates of clamping block 702 to the back pressure of lockplate Power, so that clamping block keeps latch hook 7022 to enter the state of the lockhole 301 of keeper 3, keeper 3 is hooked by latch hook 7022, it is impossible to Abjection, realizes that door closure is closed.

Lock out action

Under above-mentioned door closure closed mode, electromagnet II 804 be powered when, iron core II 805 by adhesive, together with operation panel 801 Move to left；Join pilot pin 19 on the positioning on operation panel/reseting groove platform structure and matrix as shown in fig. 13 that and make relative displacement, calmly Position pin slips into F areas and is stayed in F areas by the effect of F areas retaining wall from the E areas of at first operation panel, when the power-off of electromagnet II 804 releases iron During II 805 adhesive of core, operation panel 801 is moved to right under back-moving spring III19 effects, to operation prelaminar part insertion clamping block 702 Below locking limiting section 7023, referring to Fig. 8, Fig. 9, clamping block 702 is prevented to turn round, holding keeper 3 can not be from the lock of clamping block 702 Hook 7022 is deviate from, and locking is kept；Pilot pin is set to be reset to A areas simultaneously；Meanwhile, after operation panel 801 is moved to right, with power supply common port The end of movable contact spring 18 of the connection of son 9 obtains stress and puts an inclined distance, makes the movable contact 1801 of movable contact spring and coil terminals 1 Contact 14011 disconnect, specifically the end of movable contact spring 18 has upward curved arc convex, after operation panel 801 is moved to right, operation panel Convex portion push movable contact spring curved arc convex, by movable contact spring end depress a distance, the movable contact 1801 and coil of movable contact spring The contact 14011 of terminal 1 disconnects, and magnet coil 14 is in forces off-state.

The general domestic electric appliance of Modern Family is more, and the mutual electromagnetic interference of home appliance is frequent.Such as in laundry In machine operation process, after washing machine electromagnetic control system is subject to outside electromagnetic interference, solenoid controlled end occurs and misleads Door for washing machine is caused to be opened by mistake.The utility model under the lock-out state, the terminal of magnet coil one and power supply public terminal In off-state is forced, so when solenoid controlled end is broken down and turned on, magnet coil will not still be powered conducting, keep away Exempt from door for washing machine to open by mistake.Additionally, system establishes a wire loop by cable by detection again judges whether door lock locks.

Under above-mentioned lock-out state, even if applying an outside pulling force to keeper 3, because operation panel 801 blocks clamping block 702 Rotate, clamping block can not be pivoted, and keeper 3 can not be deviate from from the latch hook 7022 of clamping block.

Unlocking motion

Under lock-out state, then apply an electrical pulse to electromagnet II, operation panel 801 is moved to left under the effect of electromagnet II, Join pilot pin on the positioning on operation panel/reseting groove platform structure and matrix as shown in fig. 13 that and make relative displacement, pilot pin from At first the A areas of operation panel slip into D and are stayed in D areas by the effect of D areas retaining wall, when the power-off of electromagnet II releases II adhesive of iron core, Operation panel 801 is moved to right under back-moving spring III effects, and pilot pin slips into the retaining wall effect of Bing Shouci areas of E areas and stays in this from D areas Area, that is, prevent operation panel movement；Now, the front portion of operation panel 701 is deviate from from the locking limiting section 7023 of clamping block 702, referring to Fig. 9 states to Fig. 8 states, door lock assembly is in released state.Now, the front end of lockplate 701 is under the effect of back-moving spring II 13 Will the slewing limit portion 7024 of clamping block 702 hold fixation, referring to Fig. 5, Fig. 8, the state of clamping block 702 keeps, in door closure Closed mode.Meanwhile, after operation panel 801 is moved to left, the movable contact spring 18 being connected with power supply public terminal 9 loses stress reset, moves spring The movable contact 1801 of piece is closed with the contact 1403 of coil terminals one, and magnet coil loop is in closure state, makes magnet coil In can power-on operational status, system establishes a wire loop by cable and judges whether door lock unlocks by detection again.

Manual door opening action：

Before lock out action or after unlocking motion, i.e., under released state, when from washing machine to door closure opening direction Apply thrust or outside washing machine during sliding door lid, generation pulling clamping block 702 makes the counterclockwise rotation of latch hook 7022 on keeper 3 Turn power, correspondingly slewing limit portion 7024 produce the power that the front end of lockplate 701 is pushed, when the pulling force on keeper reaches necessarily During degree, being applied to the lower pressure of locking front edge of board can overcome the elastic force of back-moving spring II13 in receiving space 101, clamping block The counterclockwise rotates of slewing limit portion 7024, the front end of lockplate 701 is pressed towards lower movement, and to away from the side of clamping block 702 To moving horizontally, when keeper 3 pulls clamping block 702 to rotate to certain angle, referring to Fig. 5, Fig. 6, locking front edge of board can be from returning Turn to depart from limiting section 7024, in the presence of back-moving spring II13, lockplate 701 is reset to Fig. 4 states, clamping block 702 Rotated in the presence of button spring is turned round to Fig. 5 states, keeper can be deviate from completely from latch hook 7022 to be realized opening the door.

This door-opening mode is significant to protecting children under particular case, such as child enters in washing machine drum, door In the case that lid is finally closed, child can push door closure open with the strength of oneself, so as to avoid an accident.

Electric open-door is acted：

In the unlocked state, move to left such as figure to the on-off electric pulse of magnet coil one, lockplate 701 under electromagnetic force 10, when the front end of lockplate departs from from the slewing limit portion of clamping block, clamping block also rotated in the presence of revolution button spring 6 to Fig. 4 states, keeper can be deviate to realize electric open-door completely from latch hook.

This electric open-door mode can make user from opening Door by Hand, and washing of drum type washing machine can be made to terminate rear washing tube Interior ventilation, it is to avoid the lid that do not open the door for a long time causes mouldy smelly in bucket.
